[REVIEW 3-6] fdo#43989 Automatic restart on Windows

Backporting the fix for 
<https://bugs.freedesktop.org/show_bug.cgi?id=51252> "LO cannot start 
(reports runtime error with Visual C++ Runtime Library)" to LO 3.6.0 
(which causes LO to routinely try to restart itself now after an upgrade 
on Windows) unfortunately revealed that the fix 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=55836370ffb70a34b888f81cdacdfede8fee29cf> 
"fdo#43989: Revert 'win32-dont-attempt-restart.diff: Don't attempt to 
restart OOo after crash'" for 
<https://bugs.freedesktop.org/show_bug.cgi?id=43989> "After installation 
first launch terminates after splash screen" should have been backported 
as well.  (And the latter undoes a broken fix that has been corrected on 
master with 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=b5ad981518f4407243f89507b2561dd0b1ef28ee> 
"bnc#524250: Show backing component after cancelled recovery.")

The net effect is that, on Windows, the first start of LO 3.6.0 (both a 
completely new installation, as well as after an upgrade from older 
versions) silently terminates after the splash screen.  The user needs 
to start LO anew.  While this is unfortunate, it is IMO only a minor 
annoyance with a trivial workaround, so does not warrant yet another LO 
3.6.0 RC5.  (See <https://bugs.freedesktop.org/show_bug.cgi?id=51252#c58>.)

So, please review for cherry-picking into libreoffice-3-6 the two commits

<http://cgit.freedesktop.org/libreoffice/core/commit/?id=b5ad981518f4407243f89507b2561dd0b1ef28ee> 
"bnc#524250: Show backing component after cancelled recovery"

and

<http://cgit.freedesktop.org/libreoffice/core/commit/?id=55836370ffb70a34b888f81cdacdfede8fee29cf> 
"fdo#43989: Revert 'win32-dont-attempt-restart.diff: Don't attempt to 
restart OOo after crash'."

Thanks,
Stephan
